河流污染物移动的随机模型

河流污染物移动的随机模型 A RANDOM MODEL ABOUT TRAVEL OF POLLUTANTS IN RIVER 陈焕章 Chen Huanzhang first-author 杨麒 Yang Chi 何娟娟 He Juanjuan 本文从理论上探讨了河流污染物移动的随机过程,并提出了研究河流污染物移动和状态分布的方法。我们首先确立了反映河流污染物状态变化的状态转移矩阵,探讨了线性化系统的单位输出响应特性,接着又探讨了在输入序列X（T,t）作用下污染物的纵向贮积过程,最后简述了一下污染物的横向贮积过程。 In this paper, a random process about travel of pollutants in river is th- eore tically approached, and the methods for studying the pollutant travel is also put forward. First, we has determined the state-transmission matrixes that can reflect pollutants to travel and probed into the unit impulse respon- se characteristic for the linearized system which may be defined by the no- rmal sampling, then approached the longitpdinally accumulated process about pollutants on the input series X（T,t）, at last, studied the laterally diffused and accumulated process on pollutants in river. 随机模型 河流污染物 水污染 水质模型 Random model pollutants in river water pollution water quality model 1988-03-01 2021-04-01 3
